Abstract
There remains a low but intractable risk of rhegmatogenous retinal detachment (RRD) after surgical repair of macular holes (MHs). The purpose of this study is to identify potential causes for RRDs after MH surgery. The authors retrospectively examined a single surgeon series of stage 3 MH repair surgeries during a 5-year period. Clinical data, including preoperative, intraoperative, and postoperative evaluations, were reviewed to determine potential causes of RRD. Of the 332 eyes that received MH surgery, 12 (3.6%) developed postoperative RRD. Seven RRD cases exhibited no evident precursor pathology; however, augmented posterior hyaloid adhesions (APHAs) were found intraoperatively and postoperatively. In MH surgery, APHA increases risk for RRD. During PPV, the vitreous typically separates to the peripheral vitreous base. Some eyes have APHAs near the equator that cannot be elevated, consistent with strong adhesion. The authors believe the high postoperative RRD rate is due to continued hyaloid elevation after surgery. [Ophthalmic Surg Lasers Imaging Retina. 2019;50:635-638.].
